In cavity quantum electrodynamics, it is hard to enhance the coupling strength between quantum dot (QD) and cavity, owing to the limited choice of QDs and the positional uncertainty brought by the inhomogeneous cavity fields. In this paper, we randomly distribute N oscillators with oscillating...

We propose a simple method to deconvolute NMR spectra of quadrupolar nuclei in order to separate the distribution of local magnetic hyperfine field from the quadrupole splitting. It is based on an iterative procedure which allows to express the intensity of a single NMR line directly as a linear...

Phase equilibrium lines of hexagonal graphite (hg) and cubic diamond (cd) phases of carbon as well as a saddle-point equilibrium line between the two phase equilibrium lines are studied by first-principles total-energy calculations. The Gibbs free energies (G) of the three equilibrium lines...

The effect induced by the presence of a polaron related relaxation process on the dielectric properties of a ferroelectric KTa<Subscript>1−x </Subscript>Nb<Subscript> x </Subscript>O<Subscript>3</Subscript> (KTN) crystal was investigated (10<Superscript>-2</Superscript>−10<Superscript>6</Superscript> Hz, at 300−375 K) using broadband dielectric spectroscopy.

Several M<Subscript>3</Subscript>TeO<Subscript>6</Subscript> (M=Mn, Co, Ni, Cu) oxides order antiferromagnetically at low temperatures (≲60 K), while displaying interesting dielectric properties at high temperatures (ferroelectricity below 1000 K in M=Ni case). We have investigated and analyzed the structural and magnetic properties of...</subscript></subscript>

By the infinite time-evolving block decimation (iTEBD) technique, the quantum phase transitions (QPTs) and the ground-state properties of a spin-1/2 alternating Heisenberg-Ising chain are investigated. As the Ising coupling is generalized into the ferromagnetic case (J <Subscript> I </Subscript> 0), in addition to...</subscript>

Adsorption of oxygen on the Mo (112) surface precovered with a pseudomorphic monolayer of beryllium has been investigated at room temperature by AES, LEED and contact potential difference methods. Such a Be/Mo (112) substrate is actually a bimetallic surface where closely-packed atomic Mo...

In the present contribution we apply first principles calculations to investigate the electronic structures and stability of BN hydrogenated monolayers which include a substitutional carbon atom. For comparison, additional C hydrogenated structures are considered. The obtained results...

In this paper we systematically analyze the electronic structures of polar and nonpolar wurtzite-InN/GaN quantum dots and their modification due to the quantum-confined Stark effect caused by intrinsic fields. This is achieved by combining continuum elasticity theory with an effective-bond...

We provide an exact solution of the Efimov spectrum in ultracold gases within the standard two-channel model for Feshbach resonances. It is shown that the finite range in the Feshbach coupling makes the introduction of an adjustable three-body parameter obsolete. The solution explains the...
